• Abstract:
  Styrene-butadiene (S/B) latex modified concrete overlays are being used to protect ; new bridge decks from rapid deicer-borne chloride intrusion and also in bridge ; deck rehabilitation efforts. The purposes of this research were to evaluate several ; commercially-available S/B latex modifiers for bridge deck overlay concrete; and to ; develop chemical specifications for the material, a prequa1ification program to ; permit evaluation of other S/B latex modifiers which become available, and a certification ; program to insure the user receives a prequalified product. ; The chemical and physical properties of the latex emulsions were studied (percent ; solids, percent butadiene, particle size, surface tension, viscosity, etc.) and ; the material from each manufacturer was fingerprinted using infrared spectroscopy. ; The physical properties of concrete made with each material were also determined ; (workability, strength-compressive, f1exual and bond, freeze-thaw and scaling resistance, ; and chloride permeability). ; In general, the studies showed,that the following materials exhibit similar ; properties and thus would be expected to perform similarly as bridge deck overlays: ; Modifier A - Dow Chemical Company; Deco-Rez 4776 - General Polymers Corporation; ; Thermoflex 8002 - Reichhold Chemicals, Inc.; and Arco Dy1ex 1186 - Arco Polymers, Inc. ; The prequalification procedures given in the report are suggested for use in ; evaluating other S/B latex emulsions offered by industry. The certification procedures ; are suggested for use to insure that each production batch of emulsion is ; similar to an emulsion which was prequalified.
